Symptoms

Availability Check is looking at Quantity on Hand, not Quantity Available, where Availability Check is turned on.

Per KM helps, when Availability Checking is selected or 'ON', MRP checks available inventory balances in all branches defined in the P3403T and the available inventory at that branch will be committed until there is a zero balance and no replenishment order messages will be created at that supply branch. If the required quantity is not available in the demand branch, the system will check for on hand inventory in the supply branches set up in the P3403T and in the sequences that have been defined – See Branch Level and Branch Priority definitions.

When MRP checks available inventory balances based on On Hand and not Quantity Available, then replenishment order messages will be created at that supply branch.

Steps:

1. For example, in Demand Plant A, create an P4102 MRP planning item with Demand quantity in excess of supply.
2. Enter P3403T Branch relationship established with supply plant B with AVLC=1 enabled.
3. Supply plant has quantity on hand, but also has P4210 demand SO qty, for negative quantity available.
4. Run multiple plant planning R3483 and review P3411 messages. Supply Orders split between OT/ST transfer messages for supply plant on hand quantity and supply order for the balance, driving supply plant further negative.

Note: Replenishment order messages are created at the supply branch.
